1995 PONTIAC BONNEVILLE traction control

Cruise Control (Option)
With cruise control, you can
maintain
a speed of about
25 mph (40 kmh) or more
without keeping your foot
on the accelerator. This can
really help on long trips.
Cruise control does not
work at speeds below about
25 mph (40 km/h).
When you apply your brakes, the cruise control shuts off.
If your vehicle is in cruise control when the optional
tractison control system begins to limit wheel spin,
the
cruise control will automatically disengage. (See
“Traction Control
System” in the Index. When road
conditions allow
you to safely use it again, you may turn
the cruise control back on.

Anti-Lock Brake System Warning Light
E
ANTILOCK (@I)
With the anti-lock brake
system, this light will come
on when you start your
engine and may stay on for
several seconds. That’s
normal.
If the light doesn’t
come on, have it fixed
so it
will be ready to warn you if
there is a problem.
Traction Control System Warning Light
(Option)
This warning light
should come on briefly
as you start the engine.
r TRACTION OFF
If the light stays on, turn the ignition off. Or, if the light
comes on when you’re driving, stop
as soon as possible
and turn the ignition off. Then
start the engine again to
reset the system.
If the light still stays on, or comes on
again while you’re driving, your Pontiac needs service.
If the regular brake system warning light isn’t on, you
still have brakes, but you don’t have anti-lock brakes.
If the regular brake system warning light is also on, you
don’t have anti-lock brakes and there’s a problem with
your regular brakes. See “Brake System Warning Light”
earlier in this part.
If the warning light doesn’t come on then, have it fixed
so it will be ready to warn you if there’s a problem. If it
stays on, or comes on when you’re driving, there may be
a problem with your traction control system
and your
vehicle may need service. When this warning light is on,
the system will not limit wheel spin. Adjust your driving
accordingly.

The anti-lock system can change the brake pressure
faster than any driver could. The computer is
programmed to make the most of available tire
and
road conditions.
You can steer around the obstacle while braking hard.
As you brake, your computer keeps receiving updates on
wheel speed and controls braking pressure accordingly.
Remember: Anti-lock doesn’t change the time you need
to get your foot up to the brake pedal. If you get too close to
the vehicle in front of you,
you won’t have time
to apply your brakes if that vehicle suddenly slows or
stops. Always leave enough room up ahead
to stop, even
though you have anti-lock brakes.
To Use Anti-Lock
Don’t pump the brakes. Just hold the brake pedal down
and let anti-lock work for you.
You may hear a motor or
clicking noise during a hard stop, but this is normal.
Traction Control System (Option)
Your vehicle may have a traction control system that
limits wheel
spin. This is especially useful in slippery
road conditions. The system operates only if it senses
that one or
both of the front wheels are spinning or
beginning to lose traction. When this happens, the
system works the front brakes and reduces engine power
(by shutting off fuel injectors and managing engine
spark) to limit wheel spin.
You may feel the system working, or you may notice
some noise, but this is normal. If your vehicle is in
cruise control when the traction control system begins to
limit wheel spin, the cruise control will automatically
disengage. When road conditions allow you
to safely
use it again, you may re-engage the cruise control. (See
“Cruise Control” in the Index.)

with your traction control
To turn the system off, press
the TRACTION
CONTROL button located
on the console next
to the
gear shift selector.
See “Traction
Control System Warning Light” in the
Index. When this warning light is on, the system
will not
limit wheel spin. Adjust your driving accordingly.
The traction control system automatically comes on
whenever you
start your vehicle. To limit wheel spin,
especially in slippery road conditions, you should
always leave the system on. But you can
turn the
traction control system
off if you ever need to. (You
should
turn the system off if your vehicle ever gets stuck
in sand, mud, ice or snow. See ‘‘Rocking Your Vehicle”
in the Index.) The
TRACTION OFF warning
light will come on and
stay on. If the system is limiting wheel spin when you
press
the button, the system won’t turn off right away. It
will waif until there’s no longer a current need to limit
wheel spin.
You can turn the system back on at any time by pressing
the button again. The TRACTION OFF warning light
should
go off.

Braking in Emergencies
Use your anti-lock braking system when you need to.
With anti-lock, you can steer and brake at the same
time. In many emergencies, steering can help you more
than even the very best braking.
Steering
Power Steering
If you lose power steering assist because the engine
stops or the system is not functioning, you can steer but
it will take much more effort.
Variable Effort Steering
If your vehicle is equipped with this option, you have a
variable
effort steering system that eases steering effort
at speeds less than 20 mph (32 km/h). This is
particularly useful when parking your vehicle.
Steering Tips
Driving on Curves
It’s important to take curves at a reasonable speed.
A lot of the “driver lost control” accidents mentioned on
the news happen on curves. Here’s why: Experienced driver
or beginner, each
of us is subject to
the same laws
of physics when driving on curves. The
traction of the tires against the road surface makes it
possible for the vehicle to change its path when you turn
the front wheels. If there’s no traction, inertia will keep
the vehicle going in the same direction.
If you’ve ever
tried
to steer a vehicle on wet ice, you’ll understand this.
The traction you can get in a curve depends
on the
condition
of your tires and the road surface, the angle at
which the curve is banked, and your speed. While you’re
in a curve, speed is the one factor you can control.
Suppose you’re steering through a sharp curve. Then you
suddenly accelerate. Both control systems
-- steering and
acceleration
-- have to do their work where the tires meet
the road. Unless you have traction control and the system
is on, adding the sudden acceleration can demand too
much of those places. You can lose control.
What should you do
if this ever happens? Ease up on the
accelerator pedal, steer the vehicle the way you want
it
to go, and slow down.
Speed limit signs near curves warn that you should
adjust your speed. Of course, the posted speeds are
based on good weather and road conditions. Under less
favorable conditions you’ll want to go slower.

Loss of Control
Let’s review what driving experts say about what
happens when the three control systems (brakes, steering
and acceleration) don’t have enough friction where the
tires meet
the road to do what the driver has asked.
In any emergency, don’t give up. Keep trying to steer
and constantly seek an escape route or area of less
danger.
Skidding
In a skid, a driver can lose control of the vehicle.
Defensive drivers avoid most skids by taking reasonable
care suited to existing conditions, and by not
“overdriving” those conditions. But
skids are always
possible.
The three types of skids correspond to your Pontiac’s
three control systems. In the braking skid your wheels
aren’t rolling.
In the steering or cornering skid, too
much speed or steering in a curve causes tires to slip and
lose cornering force. And in the acceleration skid too
much throttle causes the driving wheels to spin.
A cornering skid is best handled by easing your foot off
the accelerator pedal.
If you have the traction control system, remember: It
helps avoid only the acceleration skid.
If you do not have traction control, or if the system is
off, then an acceleration skid is also best handled by
easing your foot off the accelerator pedal.
If your vehicle starts to slide, ease your foot
off the
accelerator pedal and quickly steer the way
you want the
vehicle to go. If you start steering quickly enough, your
vehicle may straighten out. Always be ready for a
second skid if it occurs.
Of course, traction is reduced when water, snow, ice,
gravel, or other material is on the road. For safety, you’ll
want
to slow down and adjust your driving to these
conditions. It
is important to slow down on slippery
surfaces because stopping distance
will be longer and
vehicle control more limited.
While driving on a surface with reduced traction, txy your
best to avoid sudden steering, acceleration, or braking
(including engine braking by shifting to a lower gear).
Any sudden changes could cause
the tires to slide. YOU
may not realize the surface is slippery until your vehicle
is skidding. Leam to recognize warning clues -- such as
enough water, ice or packed snow on
the road to make a
“mirrored surface”
-- and slow down when you have
any doubt.
Remember: Any anti-lock brake system (ABS) helps
avoid only the braking
skid.
